Android layout file does not allow characters like &, <,>

Question

When I tried to use &, <,> as text of a text view, both in main.xml and in the strings.xml file, it returns an error. I want to show "&", "<" anyway, in a text view. How to do it?

Please advise me.

Thanks in advance.

Answer 1

As pointed out by @Welbog, there are 5 XML escape sequences:

"   "
'   '
<   &lt;
>   &gt;
&   &amp;

Answer 2

I do not know Android, but in using XML

<   =   &lt;
>   =   &gt;
&   =   &amp;
"   =   &quot;
'   =   &apos;

Or use CDATAfor example

<![CDATA[
    my String with 
    special chars like
    >, < and &
    normally not allowed in XML!
]]>

1 escape XML. @mikaveli

This is XML. You have to run away from them. Maybe you should learn XML before using XML-based layout language?

< &lt;
> &gt;
& &amp;
" &quot; (in attributes)
' &apos; (in attributes)
